這類逆變器由左右二個雙向boostdc / dc變換器構成,左右二邊是對稱的,所以整個電路構成了一個四象限變換器,我們可以恰當控制各功率管的開、關,使左邊的兩象限dc / dc變換器輸出一個帶直流偏置的正弦波,使右邊的兩象限dc / dc變換器輸出一個相差180度帶同樣直流偏置的正弦波形,這樣,負載zl上的電壓是左、右兩個dc / dc變換器電壓的差動輸出,正好可以消掉直流偏置,最終在負載r1上得到的就是正弦波。Firstly, the basic theory of full - bridge phase - shift zvs pwm converters are expatiated and another three kinds of circuits of full - bridge phase - shift zvs pwm converters are discussed. there are four kinds of problems which are emphasized : how to expand the zvs range ; how to reduce the circulation in the primary side of the transformer in order to minimize the on state losses ; how to decrease the loss of effective duty circle and how to eliminate the parasitic oscillation of the output rectifiers
本文首先分析了基本的全橋移相zvsdc dc變換器的工作原理,為解決滯后橋臂不易實現零電壓開關( zvs )的情況,討論了另外三種全橋移相zvsdc dc變換器的電路拓撲,重點分析並解決了四個方面的問題:如何擴大zvs的負載范圍;減小變壓器原邊環流,降低變換器系統通態損耗;減少變壓器次邊有效占空比丟失;消除輸出整流二極體的寄生振蕩。Then the article specifies the control principle of the infrared sensor, the dust warehouse detection, the collision detection, the floating switch, the speedometer, the edge - walking detection, the keyboard, the liquid crystal display as well as the vacuum motor, the brush motor, the driver motor and etc. in the software design aspect, through analyzing the link between the bottom hardware and path coverage planning algorithm, it actualizes pid adjustment algorithm for the robot ’ s straight walking, the coordinate transformation and computation of speedometer ’ s return value, providing the basis for the route coverage algorithm
然後,詳細說明了紅外傳感器,塵倉檢測,碰撞檢測,浮動開關,里程計,貼邊行走檢測、鍵盤、液晶顯示以及吸塵電機、毛刷電機、主動輪驅動電機等控制原理。在軟體設計方面,通過分析底層與路徑規劃演算法的銜接,實現了機器人直行pid校正演算法、里程計返回值的坐標變換及計算等演算法,為路徑覆蓋演算法提供依據。Based on comparison between the parallel - parallel and parallel - serial combination ttfc, a novel two - transistor forward converter with parallel - serial / serial combination is proposed. this converter reduces greatly the current overshoot of the primary side switches and the voltage overshoot of the rectifying diodes. moreover, the size and weight of the converter can also be reduced by interleaving technique and increasing frequency
本文在對並-串型和並-並型雙管正激組合變換器進行了詳細比較研究的基礎上,提出了一種新型並-串串型雙管正激組合變換器,該組合變換器可以大大減小原邊開關管的電流應力和副邊整流電路中二極體的電壓應力;通過交錯控制及提高開關頻率,大大提高了變換器的功率密度。分享友人
